The recommended version for Rock is ruby 1.9.3, and I detected that ruby1.9.1
provides it. I am forcefully selecting it as the ruby executable. You can force
the use of another Ruby executable by passing it on the command line, as e.g.
  sh bootstrap.sh ruby2.0

The recommended version for Rock is ruby 1.9.3. I don't know if you have it
installed, and if you do what name it has. You will have to select a Ruby
executable by passing it on the command line, as e.g.
  sh bootstrap.sh ruby19
